Map 5: Incidence Rate1 of Blood Lead Levels ≥ 10 mcg/dL Among Children Under Age Six Years by County; Three-Year Average Rates, 2005 - 20072 Blood Lead Test Data, New York State Excluding New York City

Map 5 groups counties into clusters defined by the rate of incidence of BLLs ≥ 10 mcg/dL among children under age six years, expressed as the number of children identified with BLLs ≥ 10 mcg/dL per 1,000 children tested. A three-year average is calculated for incidence rates to control for instability in rates that occur due to small numbers of cases in some counties in single years. The statewide three-year average incidence rate for this time period, excluding NYC, was 10.4 incident cases per 1,000 children tested (1.04 percent of children tested). The map graphically depicts the variation in incidence rates among counties across the state. County clusters were established based on the natural break statistical method, which groups county-level incidence rate values into categories that optimize both the similarity of values within each category and the differences in values between categories. Counties with the highest rates of incidence of childhood lead poisoning are highlighted in the darkest shade, while those with the lowest incidence rates are highlighted in the lightest shade.

Incidence Rate: The total number of children under age siz years identified for the first time with confirmed blood lead levels ≥ 10 mcg/dl between 2005 and 2007 divided by the total number of children under age six years that had screening tests in that given year multiplied by 1,000.
